I only do Q1 and Q4 as I have no time
Step-by-step explanation:
Q4.
MEAN=SUM OF ALL OBSERVATIONS/TOTAL NUMBER OF OBSERVATION.
SO. 150+152+150+154+155+159+165+148+147+160+162+165+167+149+150+157+152+154+152+157+162+160+159+158+170/25
3914/25=156.56 answer.
Q1.
Given that (81) raised to the power of 5/n=243 raised to the power of 2
So, 81 can be written as
(3 raised to the power of 4) 5/n=3 raised to the power of 5 which is the exponential form of 243.
Now we know that (a)b means a×b
so. 3 raised to the power of 4×5/n=3 raised to the power of 5
now, it will become 3 raised to the power of 20/n (as 4×5=20) =3 raised to the power of 5.
(Now since the bases are same, power will also be same)
so. now calculate their powers
20/n=5
n=20/5
n=4.
